In crisp transportation, trying to fuzzify the amount of supply of the ith origin ai and
the amount of demand of the jth destination bj, we use level l fuzzy numbers and level
(l, r) interval-valued fuzzy numbers to fuzzify ai and bj in the constraints. We get
transportation problem in the fuzzy sense. We also cooperate some statistical concepts
and corresponding to (1 - £\) ¡Ñ 100% statistical confidence intervals of the amount of
supply and the amount of demand. We use level (1 - b, 1 - £\) interval-valued fuzzy
numbers to fuzzify demand and product in the constraints. Then we get transportation
problem in the fuzzy sense based on statistical data.
